What is blue light?

Blue light is a natural part of visible light, emitted by the sun. But today, it is also omnipresent because of the screens on our computers, smartphones, tablets, and other electronic devices. This light, with a wavelength between 400 and 490 nanometers, has powerful energy and can easily penetrate the skin.

While it is useful for regulating your biological clock and keeping you awake, excessive exposure to blue light can have some less-than-great effects on your skin.

Why it’s important to protect yourself

With all the time we spend in front of screens, it is essential to protect your skin from the harmful effects of blue light. Here are a few simple tips:

• Add a blue-light filter to your screens to reduce exposure.

• Choose a skincare routine rich in antioxidants to neutralize free radicals.

• Use sunscreen even indoors, as blue light passes through windows.

Niacinamide: a key ingredient for combating blue light

Niacinamide (vitamin B3) is a multifunctional active ingredient whose benefits have been scientifically proven. Here’s how it protects your skin from the harmful effects of blue light:

• Reduction of oxidative stress: Blue light generates free radicals (ROS) that damage skin cells and contribute to premature aging. A study by the DSM-Firmenich laboratory found that using 3% niacinamide can reduce free radicals by 48% after blue-light irradiation, demonstrating its protective role in the dermis.
• Repair of cellular damage: It supports the skin’s natural repair mechanisms, particularly against the combined effects of UV rays and external aggressors.
• Prevention of hyperpigmentation: Niacinamide reduces melanosome transfer, helping to diminish dark spots and even out the complexion.
• Strengthening of the skin barrier: It improves the skin’s hydration and protects it against external aggressors.

A study by the DSM-Firmenich laboratory demonstrated that niacinamide could significantly reduce markers of cellular damage induced by blue light and UV rays, while maintaining epidermal health.
